Here's the mathematica code for plotting a simple curve that has 2 different radius's
Manipulate[
ListPlot[Table[
If[t > d, {(e + 1) Cos[t], (e + 1) Sin[
t]}, {(e + 1 - c (t/(d))) Cos[t], (e + 1 - c (t/(d))) Sin[
t]}], {t, 0, 2 Pi, 0.011}]], {c, 0, e + 1}, {d, 0.011, Pi}, {e,
0, 4}]
From this maths it should be possible to plot irregular Reuleaux triangles.

How do you find the radius of curve when its not given?

[@Naughtymsa]

You are teaching this So Nice...I Love the Way You teach ..i Hope if you could be my Teacher in Field..

[@MuhammadBilal-kt6mr]

really a simple solution.,I liked

[@humbertocabrera8914]

Nice explanation but how to calculate bearing for lc or CBCurve.

[@actuallylvcci]

thanks bro

[@nazariomartins8011]

how can we find the coordinates in curve, for example every 10 ft.
in case we have only PI coordinates, Radius, etc...thank you..

Check the video call horizontal curve calculations example by Aamir survey academy and if you are interesting I got this program for Casio 9860gii

[@lalitajoshi5350]

From where did you get the formula for T? Anyone explain it to me please

[@ronjunior8260]

love mathematics e Illustration from the right angle of R perpendicular to T and angle of 30’/2 or 15’ the equation is tan(15’) = T/R therefore T = R tan(15’)

Ron Junior thank you :)
